HAMMER.

SPECIFICATION forming part of Letters Patent No. 262,468, dated August8, 1882.

Application filed April 18, 1882.

To all whom it may concern:

Be it known that I, THOMAS PARTLAN, of Rondout, Ulster county, State ofNew York,

have invented a new and useful Improvement sists in a farriers ordouble-faced hammer constructed with double heads and a socket for thehandle, arranged and combined in the manner hereinafter moreparticularly described, whereby the weightof the heads will be equallydistributed on each side of the handle, or balanced. 4

1n the accompanying sheet of drawings, Figure 1 represents a side viewof my hammer; Fig. 2, view of under side of hammer; Fig. 3, a sectionthrough a a", Fig. 2.

This invention relates particularly to farriers hammers, or hammers ofthat class which have double heads and faces; and its purpose is to giveincreased weight of metal to the heads, and at the same time distributethe weight of the heads so that they will be evenly balanced by thehandle.

To that end 1 construct my hammer with two heads, A and B. Midwaybetween these heads are formed the walls a of the handlesocket (J. Inorder to increase the weight of the heads A and B by giving them as muchmetal as possible, the sides of the socket-walls a are countersunk,permitting the sides of the heads A and B to project beyond the surfacesor sides of these walls a, giving to each head the metal that wouldotherwise have filled up the countersunk portion of the socket-walls a,so that while the solidity of the heads and the amount of metal in themis increased, yet the weight of the hammer will not be materially addedto. By this operation the (No model.)

sides of the socket-walls a are made somewhat thinner than thesocket-walls of ordinary hammers; but additional bearing-surface isgiven to these walls by extending their ends so that they project inpoints I). These projections of the socket-walls a not only add strengthto the walls, but they enable the hammer-handle within the socket O tobe more firmly secured to the hammer. The socket O is carefully formedso as to be exactly midway between the heads A and B, so that when thehandle is inserted within this socket O the weight of the hammer will beequally distributed on each side of it. Now, the result of thisconstruction is that not only are the heads A and B of the hammerrendered more solid and, having more metal in them, more enduring orlasting, but at the same time the even balancing of the hammer on itshandle will enable its user to work with it for a longer time and withless fatigue than with the ordinary hammer, for the reason that in usingit the slightest motion of the hand will turn the hammer end for end orchange its direction, its balanced condition leaving little or no deadweight tobe overcome in making such effort.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A hammer composed of the heads A I3, in which the bulk of the metalis distributed, and the sunken socket-walls a a, whereby the heads arebalanced, substantially as described.

2. In a double-headed hammer in which the bulk of the metal isarrangedin the heads, the connecting socket-walls a a, sunk below andbetween said heads and extended longitudinally to afford a com pcnsating increase ot bearing for the handle, substantiallyas set forth.
